Chael should use this time to train with bjj guys other than Shields, like Palhares or a Gracie. Also he should train with gnp idols, like Coleman and Tito, and learn how to put some fire behind the 300 punches he throws a round and use more elbows. this will help him finish fights so he doesnt have to rematch anyone, or claim he stopped fighting because the round was over, or claim he didnt tap out. If Chael had better power and sub defense on the ground he would be a champ right now.
